\caption{MdMRE and Pred(25) results for Cocomo81 dataset. The column \textbf{\textit{k}} lists the \textit{k} values. $+N$ stands for non-uniform weighting. Cocomo81 results confirm that: 1) Neither the bandwidth nor the kernel type have a significant effect on the performance and 2) N-ABE methods cannot outperform the U-ABE method of ABE0.}
